BURGLAR-ALARM HOUSE-PROTECTOR.

SPECIFICATION forming part of Letters Patent N 0. 791,349, dated- May 30, 1905.

Application filed August 14,1901. Serial No. 71,877.

To all lull/m it 777/(by concern:

Be it known that I, JOSEPH LYON, a citizen of the United States,residing at Dayton, Montgomery county, Ohio, have invented a certain new and useful Burglar-Alarm House-Protector, of which the following is a specification, reference being had to the annexed drawings, forming part hereof.

My invention relates to improvements in burglar-alarm house-protectors; and it consists of the means, combinations, and arrangements and subcombinations of the various parts and means, all as hereinafter described, and set forth in the claims.

The means best known to me at this time for accomplishing the objects of my invention are illustrated in the accompanying drawings, in which- Figure 1 is an exterior view of a portion of a door embodying a portion of my invention. Fig. 2 is an interior view thereof. Fig. 3 is a sectional view of one of the bolt-keepers on line X X of Fig. 4. Fig. 4 is a sectional side View on line X X of Fig. 3. Figs. 5 and 6 are detail views. Fig. 7 is an enlarged sectional plan view substantially on line X X of Fig. 8. Fig. 8 is a sectional elevation view substantially on line X X of Fig. 7. Fig. 9 is a sectional end view substantially on line A A of Fig. 8. Fig. 10 is an elevation view of a further portion of my invention, parts thereof being broken away for clearness. Fig. 11 is a plan view of the parts shown in Fig. 10, the section being taken substantially upon line X X of Fig. 10. Fig. 12 is a detail view of one of the sliding bolts. Fig. 12 is a view of the key for unlocking said look from the outside. Fig. 12 is a front elevation view of an annunciator and alarm.

In said drawings, 10 represents the door, and 11 itsjamb. In said door 10 are slidingly mounted three bolts 14:, 15, and 16, the bolt 1 1 being operated by the knob 13 and bolt by a key adapted to be inserted in the lock 12, while bolt 16 is the night or alarm bolt. All of said bolts are provided with keepers located in the jamb11, those for bolts 14 and 15 being preferably of the usual form and that for the bolt 16 being shown in Figs. 3, 4,

7 8, and 9 and having a keeping-opening 17 larger than the bolt 16, so that when only the bolt 16 is obstructing the opening of the door said door may be moved open the extent of the play of said bolt 16 in its keeping-opening 17. This limited opening of the door is adapted to send in an alarm in the manner hereinafter set forth, and to provide a substitute for an electric call-bell, a night-lock, and to at alltimes prevent the accidental sending of an alarm said three bolts are employed in combination when desired. For instance, should aneighbor mistake the house and turn the knob 13 and withdraw the knob-controlled bolt 1e and press inward upon the door 10 the bolt 15 when in its keeper would prevent the limited movement of the door and the sounding of an alarm, and when bolt 15 is left out of its keeper in anticipation of callers who from prevailing darkness, defective vision, or other causes might not be able to find the ordinary call-bell button such callers may readily grasp and turn the knob and press inward upon the door to cause bolt 16 to sound a notification of their arrival through the instrumentalities hereinafter specified.

Thekeeper of bolt 16 is in the instance shown formed of a face-plate 18, from the rear side of which projects an angle-plate 19, said opening 17 on plate 18 being within the angle formed by plate 19. (See Figs.3, 4:, and 9.) Insulated from and secured to said keeper for bolt 16 is a plate 20, adjacent said opening 17 and electrically connected by wire 21 with an electric circuit. Also mounted in said keeper is a plate 22, projecting toward and substantially into said opening 17 and at right .an gles with said plate 20, electrical connection being normallymaintained between plates and 22 when bolt 16 is not in its keeper by projection 23 of plate 22 contacting with projection 24 of plate 20, Figs. 3 to 6, said plate 22 being electrically connected by wire 25 in the same circuit with wire 21. hen bolt 16 enters its keeper, it contacts with plate 22 and separates said projections 23 and 2 1 and breaks said electrical circuit. Intermediate and normally free from contact with bolt 16 and plate 20 is a yielding member or pin 26,

Figs. 3, 4, and 9, and in the instance there shown is slidingly mounted in projection, 27 of plate 19-and is normally held out of contact with plate by spring 28, said pin 26 projecting into the path of the limited lateral movement of bolt 16 in opening 17 of its keeper, (see Fig. 9,) so that upon such lateral movement of said door carrying said bolt 16 said pin 26 will be pressed into contact with plate 20 and the electrical circuit completed from wire through plate 19, projection 27, pin 26, plate 20, to wire 21, and the alarm thus sounded, spring 28 having sufficient tension, when desired, to resist the movement of the door and bolt 16, due to slight pressures, and prevent the sounding of an alarm by a slight movement of the door caused by light pressure upon the door, while when bolt 16 is withdrawn, either by the picking of the lock or otherwise, said plate 22 assumes its normal position, with projection 23 in contact with projection 24 of plate 20, and the alarm thus sounded by the completing of said electrical circuit. Said bolt 16 is slidingly mounted at one end in a face-plate and at its opposite end in a projection of plate 31, secured to face-plate 30. Said bolt 16 and plate 31 are in the instance shown mortised into the door 10, as shown in Figs. 7 and 8, a recess 32 being formed for the accommodation of bolt 16 when it is withdrawn from its keeper. In the inner face of the door 10 is formed a slot 33, communicating with the mortised opening for said bolts, and through said slot 33 projects a pin 34;, removablysecured to bolt 16 by screw-threads, Fig. 7, or otherwise, whereby said bolt 16 may be readily operated from within. To enable said bolt 16 to be operated from the outside of the door when said bolt 16 is in certain positions, a T-shaped slot is formed in the outer side of said bolt 16, the horizontal branch of said T-shaped slot being open at the top. Projecting from the outer face of said door and seated in said plate 31 adjacent said T-shaped slot is a keybarrel 35, having mounted therein the member 36, revolved by means of the proper key, Fig. 12, as is well known in locks of the Yale type. Upon the inner end of this revoluble member 36 is rigidly secured a plate 37, having projecting from substantially opposite portions of its periphery the shoulders 38, adapted alternately to be brought into contact with pin 39 as said member 36 is revolved, by means of a key, a half-revolution in one direction or the other. From plate 37 projects a pin 10 normally into the horizontal branch of said T-shaped slot, the normal position of said member 36 being, with one of said shoulders 38, in contact with said pin 39..

The position shown in Figs. '7 and 8 is such that bolt 16 may be withdrawn from its keeper by the turning of member 36 with a suitable key, pin 40 engaging in the vertical member of said T-shaped slot by reason of the revoluble movement of member 36, which member carried said pin 10, and when bolt 16 is completely withdrawn from its keeper said pin 1O is by the arc-shaped path of its movement again brought into the path of said horizontal member of said T-shaped slot. The member of the household can then open door 10 after having withdrawn the bolt 15 by a key in the ordinary manner and the withdrawal of latchbolt 14 by the turning of the knob 13. When inside the door, it is shut, and latch-bolt 14 enters its keeper automatically in the customary way, and bolt 15 is moved into its keeper by a key from the inside in the usual manner. If such member of the household is the last onein, he slides the bolt 16 into its keeper by means of the pin 341, which brings the vertical member of said T-shaped slot in the outer face of bolt 16 out of the path of movement of said pin 1O, so that said member 36 cannot be operated in either direction, it being locked from movement in one direction by pin 40 engaging with the wall of said horizontal member of said T-shaped slot and in the opposite direction by pin 39 contacting with a shoulder 38. Thus said night-lock is transformed into a non-pickable lock, which could only be entered by sawing through the bolt 16, to prevent which said bolt 16 is provided with a cylindrical longitudinal cavity in which is loosely mounted a hardened steel pin 41, Figs. 3 and 4. Should said bolt 16 be sawed into, the saw will strike said pin 11, upon which it can take no hold, as said pin 41 is harder than the saw, or said pin 41 revolves and turns the saw even should it happen to take hold of said pin 41. To prevent pin 41 from coming out of its cavity in bolt 16, a plug 42, Fig. 9, closes the end of said cavity.

The key-barrel 35 is mounted in plate 31 as follows: A circular opening 43 is formed in plate 31, its diameter being slightly larger than that of barrel 35. In one side of said opening 13 is formed a recess having a plurality of flat faces 1 1 adapted to engage in correspondingly shaped recesses in the periphery of said barrel 35, said engagement being effected by inserting barrel 35 through opening 43 and registering its recesses with their engaging faces 1st and then relatively moving said barrel 35 and plate 31 until said barrel 35 is seated with its recesses engaging said faces 44. A screw 15 is then inserted through face-plate 30 and threaded into the portion of said barrel 35 projecting through said plate 31, which screw 45 retains said barrel 35 in normal position.

Every hinged door and window is provided with the bolt 16 and its keeper, while the sliding windows are provided with the following alarm means: Upon the top of the lower sash is secured a bearing-plate 51, upon which is slidably mounted in any suitable manner a plate 52, provided with projections 53, to which is pivotally connected a bolt 5+1,

having its branch upon one side of said fulcrum-point projecting toward the upper sash 55 in the path of a plurality of pins 56. The opposite arm of said bolt 54 projects toward the Window-casing, which is provided with a plurality of keepers for said bolt, which may be the same as the keeper for bolt 16, hereinbefore described, and is shown in Figs. 10 and 11 to be the same in construction, the contact-spring 57, Fig. 10, being substituted for the spring-pressed plunger-pin 26. The bolt 54 is slid into one of its keepers by sliding the plate 52, carrying said bolt 54, and said plate 52 is held in positions of adjustment by clamp-screw 58.

When bolt 54 is Withdrawn from or moved vertically in its keeper, an electrical circuit is formed and an alarm sounded, as has been heretofore described for bolt 16. The two keepers for bolt 54, arranged a slight distance apart, permit the lower sash 50 to be locked in a ventilating position, and when in either keeper said bolt 54 will be adapted to be operated by any movement of the upper sash 55 by means of said pins 56, while said upper sash 55 can also be locked in a ventilating position by the arrangement of said pins 56. Said bolt 54 is provided with a pin 41 in the same manner and for the same purpose as said bolt 16.

Electrical connections are made with the bolt-keepers and their contacting devices of each separate door or window, with an annunciator of the usual or any desirable form, (shown in Fig. 12 having bell 60,) said connections being made in the usual manner for 'annunciator systems, and at each place where the circuit is completed an alarm will be sounded and the corresponding indication made, and said alarm will continue to be sounded as long as the electrical circuit is maintained at any place or places.

As is illustrated by the foregoing exemplification of my invention, its prime or fundamental object, as well as the greatest benefits and advantages of its accomplishments, is the great security to person and property and the peace of mind derivable from the use of my invention, such security and peace of mind being almost wholly derivable from the structural fact that an alarm or notice is given of an attempted intrusion at a time when the alarm-bolt bars the intrusion of the intruder, and which great benefit and advantage is due solely to the structural fact that the alarmbolt and its keeper have a relative lateral movement, and the alarm mechanism is such that an alarm is sounded or notice given upon such relative lateral movement. This accomplishment may be said to be the step between the perfect and the imperfectbetween success and failurefor otherwise an alarm would only be sounded as the intruder was intrudingthat is, after all bars to his intrusion had been removedand an alarm or notice of such intrusion would be practically as bad as no notice or Warning at all, for the intruder would have great advantage over those intruded upon by reason of their being taken by surprise by the simultaneous intrusion and notice thereof and without time to prepare to resist such intrusion. Further than this, my invention is such that in its embodiment shown and described it will acquaint those within of the character of the intrusion-that is, whether it is an attempted intrusion or an actual intrusion. here the intruder is still barred by the alarm-bolt, every attempt to intrude will result in a relative lateral movement of the alarm-bolt and its keeper, and intermittent notices or alarms of such attempts at intrusion will result, whereas when the intruder has gained entrance the alarm-bolt will have been removed from its keeper, and a continuous notice or alarm will result.

Inasmuch as I could not claim the hereinbefore-described door-locking mechanism independent of the alarm or electric circuit forming mechanism, I have set forth and claimed said door-locking mechanism in another application, filed January 13, 1902, Serial No. 89,623, entitled Locks. Since I cannot claim the hereinbefore-described mechanism for fastening the windows with as well as independent of the alarm mechanism, I have set forth and claimed said mechanism independent of the alarm in another application filed January 13, 1902, Serial No. 89,624, entitled Ventilating window-fastener, and said mechanism in combination with said alarm in another application, filed July, 1902, entitled Burglar-alarm window-fastener.
